Don't really understand what you are meaning. International's paints are more expensive than Hempel, at least up here, and come in different kinds (cruising, racing, hard) as do all the other brands.
Used to paint international bottoms. I suspect that J-Lo and Kylie are customers and that Lakey can prove it
Tried it on a canal boat a while back, that spent a few weeks in an then came out for a time on a trailer and so forth. Certainly didn't seem to affect fouling one way opr the other as the area just made for green slime anyway.
look on yachtpaint.com it's a cheap hard antifouling suitable for sail and power low speed vessels... obviously the equivalent to cruiser uno which is erroding.
